Breeding Report

I would like to thanks Frank Stopper:

Frank Stopper kindly gave me the following remarkable breeding report. For all Dwarf Puffer lovers and prospective breeders this report will be required to read, with its really interesting observations and the great pictures.

 

Breeding – Dwarf Puffer
(Nov.-Dez. 2005)

From courtship behavior, the egg-laying to the first eating of food and the free-swimming fish of the dwarf ball:>

Since 4 years I have got Dwarf Puffers (Carinotetraodon travancoricus), and I was able to get some experience in the attitude and behaviour of these interesting fishes. I keep the fish in an exlusive genus tank. In previous years, I kept my Dwarf Puffers with ohther fishes. At that time I could not observe any courtship behavior of the Dwarf Puffers.

In the summer of this year I set prepared my 60cm - Tank , as (almost) pure genus tank with the crew of 6 Dwarf Puffers, some Armano shrimps and 2 catfish (for the algae destruction), end October 05 I observed the first mating behavior in the Tank. In the next few days I provide me a great bunch Java moss (20 * 10 * 10 cm volume), which should serve as substrat for the eggs, and placed it in the aquarium between front pane and a root wood. In the meantime the courtship behavior took place every day (and almost always on time between 16 pm and 19 pm). But only when the Java moss was placed in the tank, I could also spawn behaviour with oviposition (close snuggling and getaway and leaving the Java moss from the female fish at the end of the egg-laying) inside the bunch of Moos.

Eggs were first though not to be seen. Only about 2 days later in the late evening when the light was off with the aid of a flashlight I was able to notice in the tank some eggs on the ground under the basic package . The next morning I removed the Java moss out of the tank dig eggs like gold. .This process of leaching was similar as digging for Gold in a river. With normal room lights it was not possible to see the eggs. I gave the eggs (about 8 pieces) to a separate tank (12 liters), with half of that water from the pool of adults and half with fresh tap water. I arranged the temperature in this small breeding tank at 28 ° C. In addition, I put two flat Filter pads in the tank, where micro-organisms could settle. I made a water daily exchange of about 1 liter with the same mixture of old and fresh tap water, and hoped so to keep clean the tank with the eggs.
A large part of the eggs, however, got victims of fungal. These losses probably caused by the not yet fully established tank. At the beginninthe losses of eggs caused by fungal was the biggest problem in the breeding, although I had added Biostarter and tried to optimze the water conditions . Only 2 or 3 larvae managed it in the early period after 5-6 days from the eggs to hatch. Another significant portion of the larvae could not fully lured blast and died the next day in the semi-hatched condition.

In the meantime the Puffer Parents in the large tank almost every day laing some eggs (up to 10 pieces per day) in the Java moss. The eggs were stored in or under the Java moss , always when I observed courtship behavior in the tank I collected at the next morning the eggs of the previous day . During this period the Fishes need very good and also very much food, as the permanent Spawning and the courtship process very stressful for the animals. I fed at the time (even before the first mating behavior) is only live feed in all variations (red + white mosquito larvae (bloodworms) and snails).

The high number of eggs stored gave me some leeway to experiment. To inoculate the tank water with micro-organisms and zooplankton I have taken a few liters with mud from the groundwater out of our garden pond and gave a portion of the water and Plankter in the breeding tank. In addition, I reduced the carbonate hardness of the water, I change the water distilled water blended, so make it easier to blast the skin of the eggs. After 3 weeks I still did not manage that only one of the few hatched survived longer than 4-5 days after the first egg-laying of the females Puffers. The hatches live about 4 - 5 days from their yolk bag and reach a sizeabout 3 mm. The first 3 to 4 weeks, I tried to keep clean the water in the breeding tank by just daily changing water with the new Water. While the losses were by fungal over time with the growth of micro-organisms becoming smaller, but all hatches died after exhausting their yolk bag after 5-6 days. In the meantime, I could set up in the breeding tank living Food e.g. Cyclops as primary food for the hatches. The Hatches were still dying.
I believed it depended on the deterioration of water quality due to the addition of large amounts of live feed (in the form of micro worms and freshly hatched artemia) for feeding the hatches after the exhausting of their yolk bag and bought me after an airless sponge filter, the water is clean. by a miracle survived after the commissioning of the filter almost all juveniles clutches of the newer, even on the critical limit of 5-6 days, and began about 6 days after hatching from the polyps feed intake.

After 7 the day started Puffers finally releasing fish swimming in the breeding tank and this is in the style of females. In the days before the young animals are almost exclusively on the floor or hide in the Java moss.

I suspect that ultimately especially the lack of oxygen supply for the initial mass death of juveniles was responsible. I mistakenly thought that I by the tank run into Java moss and the daily interactions of water a sufficient oxygen supply could be guaranteed. Additionally, I found a slight improvement in the slip rate by the "softening" of the water in rearing ponds (about 2 degrees of hardness from 10 to 8 sera sera)). However, even with the newer Located larvae are still some who are not fully or in part with the wrong body part first lured from the slip and dying.

A unique feed intake during the first 10 days of life, I was able to because of the small size of the juvenile fish are rarely observed. 6 days after hatching, the first micro eats worms. Alreadyat this age the behavior of juveniles in the feed intake can be compared with that of the females in the seizure of bloodworms , but the micro worms only about 2 mm long and the young fish 3-4 mm in size.
Fresh male Artemia- Nauplien are much larger than worms and micro been with me only after 7-8 days. By observing at the feed intake, I came to believe that only young animals "learn" had what is edible and what is not.
Through observations with a magnifying glass, I discovered that, along with the naked eye is not visible microorganisms by juveniles and to be focused. It raises the question of whether such microorganisms in the first days after the exhausting yolk bag for the survival of young animals are necessary or not. Maybe it was the absence of such microorganisms another reason for the initial juvenile fish dying in my pelvis?

 

 

5 Essential things for a successful spawning and Laichstimulation of dwarf fish ball:

  1. A pure species basin (at least without other predatory fish species, such as for example characins) - Armanogarnelen and Otoclinuswelse to combat algae can also socialized during the spawning season.
  2. A big bunch Java moss (as Laichsubstrat; At least 20 * 10 * 10cm volume)
  3. A water temperature of 27-28 ° C
  4. Good and especially frequent live feed (red + white mosquito larvae)
  5. Dwarf puffers both sexes

5 5 Essential things for the successful hatching and rearing of young fish dwarf ball:

    A small any breeding pools (12 liters; With micro-organisms and zooplankton)
  1. A sponge air filter (for example BIOCLEAR of Europet)
  2. A small bunch Java moss (as a hiding place for young fish and larvae)
  3. Micro worms (small) and Artemia breeding (breeding food for the young fish)
  4. Temperature in breeding pools from 28 ° C (25-watt heater rule set)
